InfoWorld's Peter Wayner provides an in-depth comparison of four Java cloud platforms, putting CloudBees, Google App Engine, Red Hat OpenShift, and VMware Cloud Foundry through their paces to 'reveal the pleasures and perils of coding on a public cloud platform.' 'The danger of lock-in seems to lurk around every corner, and that's not necessarily the worst part. What if we're happy with everything about our cloud except we need one missing feature that the cloud's masters either can't or don't want to deliver?' Wayner writes. 'Some of the clouds rely upon standard tools that take standard WAR files and deliver their information to the world. Others have so many proprietary twists that you might as well tattoo the code on your arm -- it's going to be with you for the rest of your life.'
